A Houston search for a missing pregnant woman whose due date is fast approaching has been suspended until investigators uncover new information, Click2Houston.com reports.

Tierra Adams, 25, has been missing for 15 days, and is due to give birth Thursday. Texas EquuSearch crews had been conducting ground and air searches for Adams before crews suspended the search.

Adams was last seen on Jan. 29 around 1 a.m., after she and her boyfriend reportedly fought on the way to her mother's house, khou.com reports.

Adams family says during the argument she got out of the car on the side of the road.

"Being out here in the dark, you know, anything could have happened," Frank Black of Texas EquuSearch told khou.com. "And no one has seen her. There have been no tips or leads as to her being seen any place, and that bothers us."

Adams' boyfriend has not contributed to the search, but is not currently considered a suspect, khou.com reports.
